This Leech is actually a Primeval Ice Leech. Her core has melted down going from Ice to Water.
If you cut her her blood has a clear viscous gel-like feel to it like Aloe. She also is slightly plump with water in her body, drinking said water causes hallucinations of either good or bad qualities.
However the gel/watery blood has been known for having great healing properties.
